Book excerpt: The proper implementation of pavement preservation techniques can extend the life of a pavement structure in a cost-effective manner. For this reason, a large part of the Texas Department of Transportation (TxDOT) annual budget is assigned to the maintenance and rehabilitation of the State highway network. Within this budget, a fair share is allocated to the implementation of preventive maintenance (PM) techniques, whose timely application has proved the best approach to keep the pavement sections in “Good” or “Very Good” condition. The main objective of this research study was to develop a probabilistic life-cycle cost analysis (LCCA) that allowed the evaluation and comparison of highway pavement sections subjected to one of the three main PM treatments used in Texas, namely, chip seals, microsurfacing and thin overlays. Effective life and the cost per mile lane were the main variables used to develop the analysis. The analysis was performed through Monte Carlo Simulation using data from TxDOT databases containing historical information on more than 14,000 projects constructed between 1994 and 2016. Because TxDOT maintains a plethora of information on its databases, the methodology to use those databases and to extract the relevant information used in this study was also described. During the study, the effect of the facility type, traffic volume and traffic loads on the treatments were also analyzed. Based on the results of the analysis, it was established that all three treatments present a similar service life regardless of external factors, but have different costs, with chip seals having the lowest, followed by microsurfacing and thin overlays. Findings suggest that chip seals have the most cost-effective LCC, even in environments where they are not commonly employed, like heavily trafficked sections. However, microsurfacing emerges as an interesting alternative as traffic volumes and traffic loads increase. Finally, thin overlays are to be evaluated in a case-by-case basis as they have the less predictable behavior. This is most probably consequence of being the newest type of treatment, having the steepest learning curve. They could work well in pavement sections located in intersections, turning points and stop signs, where higher shear stresses are involved.

Available in PDF, EPUB and Kindle. Book excerpt: Given the aging of highway pavements, high traffic levels, and uncertainty of sustained preservation funding, there is a need for balanced decision-making tools such as LCCA to ensure long-term and cost-effective pavement investments. It has been shown in past research that more effective long-term pavement investment could be made at lower cost using LCCA. Current LCCA-based pavement design and preservation practice in Indiana could be further enhanced by due consideration of user costs. Also, the existing FHWA LCCA software could be further enhanced for increased versatility, flexibility, and more specific applicability to the needs of Indiana, particularly with regard to treatment cost estimation and development of alternative feasible preservation strategies (rehabilitation and maintenance types and timings). The study documented/developed several sets of alternative pavement design and preservation strategies consistent with existing and foreseen Indiana practice. The preservation strategies were developed using two alternative criteria – trigger values (pavement condition thresholds) and predefined time intervals (based on treatment service lives) and are intended for further study before they can be used for practice. These strategies were developed on the basis of historical pavement management data, existing INDOT Design Manual standards, and a survey of experts. The study also found that with a few enhancements, FHWA’s current LCCA methodology and software (RealCost) could be adapted for use by INDOT for purposes of decision support for pavement investments and proceeded to make such enhancements.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents a summary of pavement preservation activities and recommended uses, expected longevity, and expected pavement life extension. It also includes some basic information intended to be used by those less familiar with pavement preservation, pavement management, life cycle cost analysis, cost estimating, contracting methods and others to help inform and educate in this important aspect of pavement engineering. Tools and techniques are presented to assist local agency engineers in evaluating costs, benefits, timing, longevity, and the decision-making process for developing an effective pavement preservation program on an individual pavement segment or over an entire network. The report includes examples using real pavement engineering data from several cities and counties in Minnesota to demonstrate topics such as activity timing and the benefits of a preventive maintenance plan rather than a reactive one. A set of guidelines was developed as part of the associated project intended to serve as reference material and as a training program.

Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to highway agency executive management including administrative, budget, and finance personnel; pavement design, construction, and maintenance engineers; and maintenance operations personnel, including supervisors and maintenance crew leaders. This synthesis describes the state of the practice with respect to setting a coherent strategy of cost-effective preventive maintenance for extending pavement life. This report of the Transportation Research Board describes the practices of state, local, and provincial transportation agencies that are attempting to minimize the life-cycle costs of pavements and are identifying, during the design of the pavement rehabilitation, reconstruction, or construction projects, the future preventive maintenance treatments and the timing and funding for those treatments. It includes a review of domestic literature and a survey of current practices in North America. The appendices include a primer on pavement design and construction, the benefits of preventive maintenance of pavements, a summary of the questionnaire data collected, a simulation of pavement management strategies, and an example process to demonstrate the cost- effectiveness of preventive maintenance.
